Metrico-Fu / Rcov “No File di analizzare”

Question

Sto cercando di ottenere metrico-fu in esecuzione su un progetto di rotaie con cui sto lavorando. Ogni volta che viene eseguito la parte rcov delle metriche ottengo:

** Invoke metrics:all (first_time)
** Execute metrics:all

No file to analyze was found. All the files loaded by rcov matched one of the
following expressions, and were thus ignored:
[/\A\/System\/Library\/Frameworks\/Ruby\.framework\/Versions\/1\.8\/usr\/lib/,
 /\btc_[^.]*.rb/,
 /_test\.rb\z/,
 /\btest\//,
 /\bvendor\//,
 /\A\/Library\/Ruby\/Gems\/1\.8\/gems\/rcov\-0\.9\.7\.1\/lib\/rcov\/formatters\/base_formatter\.rb\z/,
 /\bvendor\//,
 /\bconfig\//,
 /\benvironment\//,
 /\/gems\//,
 /\/Library\//,
 /spec/]

You can solve this by doing one or more of the following:
* rename the files not to be ignored so they don't match the above regexps
* use --include-file to give a list of patterns for files not to be ignored
* use --exclude-only to give the new list of regexps to match against
* structure your code as follows:
      test/test_*.rb  for the test cases
      lib/**/*.rb     for the target source code whose coverage you want
  making sure that the test/test_*.rb files are loading from lib/, e.g. by 
  using the -Ilib command-line argument, adding  
    $:.unshift File.join(File.dirname(__FILE__), "..", "lib")
  to test/test_*.rb, or running rcov via a Rakefile (read the RDoc
  documentation or README.rake in the source distribution).

Esecuzione rcov di per sé si presenta con lo stesso problema. Sto usando Rspec e non TestUnit se questo aiuta.

Answer 1

Se si sta utilizzando rastrello per lanciare metric_fu è possibile aggiungere qualsiasi directory Rcov percorso con questo frammento:

begin  
  require 'metric_fu'
  MetricFu::Configuration.run do |config|  
     config.rcov[:rcov_opts] << "-Ispec"  
  end 
rescue LoadError  
end

Questo aggiungerà la -Ispec bandiera per Rcov opzioni, che a sua volta aggiungere la directory 'specifica' al percorso di rcov.

Answer 2

Ho rimosso la directory "test" e ha aggiunto "--include spec / spec_helper.rb" per l'hash di configurazione Rcov. Penso che debba essere specificamente per l'helper specifiche e bisogna rimuovere la directory di prova, altrimenti tenta di eseguire rcov su TestUnit e non RSpec.

Spero che questo aiuta altre persone!

Answer 3

Quindi rcov fa questa cosa in cui viene visualizzato il "Nessun file da analizzare è stato trovato." messaggio quando il problema è in realtà l'analisi dello stack sotto il messaggio. Si potrebbe provare ad aggiornare la versione di rcov (quale versione stai?).
